General Description

Calcium carbonate (chemical formula CaCO3) is a common substance found in rocks as minerals such as limestone, marble or chalk. It is also the main constituent of shells of marine organisms, pearls, and eggshells. Calcium carbonate is a white, odorless powder or colorless crystal. Calcium carbonate in its pure state has low solubility in water, but it can easily dissolve in acid, releasing carbon dioxide.
